Can I use custom functions with $.fn.dataTable.render.text and $.fn.dataTable.render.number

Using `$.fn.dataTable.render.text()`

To combine `$.fn.dataTable.render.text()` with a custom function, you can do the following:

php
$textRenderer = $.fn.dataTable.render.text().display;

return DataTables::eloquent(User::select())
    ->addColumn('name', function($user) use ($textRenderer) {
        return $textRenderer($user->name);
    })
    ->toJson();

This will use the `$.fn.dataTable.render.text().display` function to escape the HTML in the `name` column, while allowing you to add custom logic within the closure.

Using `$.fn.dataTable.render.number()`

Similarly, you can combine `$.fn.dataTable.render.number()` with a custom function:

php
$numberRenderer = $.fn.dataTable.render.number(',', '.', 2, '$');

return DataTables::eloquent(User::select())
    ->addColumn('salary', function($user) use ($numberRenderer) {
        return $numberRenderer($user->salary);
    })
    ->toJson();

This will use the `$.fn.dataTable.render.number()` function to format the `salary` column, while allowing you to add custom logic within the closure.

Using `columnDefs`

Alternatively, you can use the `columnDefs` option to apply the renderers to specific columns without having to redefine all the columns:

php
return DataTables::of(User::select())
    ->addColumn('name', function($user) {
        return $user->name;
    })
    ->addColumn('salary', function($user) {
        return $user->salary;
    })
    ->columnDefs([
        [
            'targets' => 0,
            'render' => $.fn.dataTable.render.text().display
        ],
        [
            'targets' => 1,
            'render' => $.fn.dataTable.render.number(',', '.', 2, '$')
        ]
    ])
    ->toJson();

This will apply the `$.fn.dataTable.render.text().display` function to the `name` column and the `$.fn.dataTable.render.number()` function to the `salary` column, without having to redefine all the columns.

The key points are:

1. Use the `$.fn.dataTable.render.text().display` function to escape HTML in a column.
2. Use the `$.fn.dataTable.render.number()` function to format a numeric column.
3. Combine these renderers with custom functions within the column definition closures.
4. Use the `columnDefs` option to apply the renderers to specific columns without redefining all columns.
